Subject: qemu-nbd: Fix return value handling of bdrv_open
X-Git-Tag: v0.13.0-rc0~960
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=a16c174c51e7cd896c701d5d0e8329e610e90ce1;p=qemu.git

qemu-nbd: Fix return value handling of bdrv_open

bdrv_open may return -errno so we have to check
if the return value is '< 0', not '== -1'.
